Application of zeolite improves water and nitrogen use efficiency while increasing essential oil yield and quality of Salvia officinalis under water-deficit stress

Barley is the primary matrix for malting process of beer production. Farmers count on increasing cultivation inputs, especially nitrogen fertilization, in order to reach a higher yield. Nevertheless, an overuse of nitrogen, besides causing environmental damages, can determine a deterioration of quality traits of malting barley, in particular an increase in grains protein content, which should range between 10 and 11% as required by the mating industry. Over two successive years, barley was grown under 4 different nitrogen (N) doses—0 kg N ha−1—N0; 20 kg N ha−1—N20; 40 kg N ha−1—N40 and 60 kg N ha−1—N60, and subject to a biostimulant treatment (Ecklonia maxima seaweed extract). Barley yield and growth parameters increased with nitrogen and seaweed application. N40 was already sufficient in the second year to reach the plateau of the highest production. Biostimulant application increased 17.9% the nitrogen use efficiency, 15.7% the biomass production, and 17.0% the yield with respect to untreated plants. Our results indicate that a significant reduction in nitrogen is possible and desirable, combined with the application of a plant-based biostimulant like seaweed extract, which determines an improvement in nitrogen use efficiency, assuring a higher production and lower fertilization inputs.

Abstract An essential approach to reduce drought in plants is to maximize the use of most limited resources. The increase in water-use efficiency (WUE) is important to maximally utilize the available water to increase photosynthesis and growth of plants under water-deficit stress. Both WUE and photosynthetic nitrogen use efficiency (PNUE), as the indices of resource-use efficiency were studied in mustard (Brassica juncea L.) plants grown under limited water conditions with low-N (100 mg N kg−1 soil) and sufficient-N (200 mg N kg− 1 soil) N and sprayed with 0- and 0.5 mM salicylic acid (SA). Application of SA increased water potential, osmotic potential, WUE and incorporation of soil N into photosynthetic machinery by enhancing PNUE. It also increased photosynthesis of plants maximally by increasing stomatal conductance and intercellular CO2 concentration under water-deficit stress. This increase was greater in the presence of sufficient-N where 0.5 mM SA maximally enhanced the N-metabolism, redox ratio that mitigated the oxidative stress. The application of SA on plants supplemented with N reduced ethylene and abscisic (ABA) synthesis. It could be inferred that SA enhanced N utilization at its optimal level to maintain redox ratio and inhibit ABA-mediated stomatal closure to enhance the resource utilization and photosynthesis. SA also enhanced glucose utilization which prevented photosynthetic repression by enhanced glucose under stress. Thus, SA application may impart a potential management tool for increasing photosynthetic NUE, WUE and photosynthesis under drought.

Durum wheat is often cultivated in marginal areas with great management difficulties. Organic fertilization is a sustainable agricultural practice that allows preserving the environment, but its limit can be the reduction of yield and quality of crops, also in cereals. The aim of research was to evaluate the effects of the organic fertilization on yield and quality of Simeto, a variety of durum wheat, cultivated for two years in three different sites of the internal hill of Campania Region (San Giorgio la Molara, SGM; Ariano Irpino, AI; Sant’Angelo dei Lombardi, SAL). SGM was a sandy-clay-loam soil, with high fertility, while AI and SAL were clay soil. The organic fertilization (ORG), based on roasted leather, was compared to mineral fertilization (MIN) and the not fertilized treatment (N0). In SGM, crop growth rate (CGR) and leaf area index (LAI) were significantly higher than AI and SAL until the flowering (about 2- and 4-fold more, respectively). MIN and ORG significantly boosted CGR compared to N0, while for LAI, ORG was never different from N0. The two-years value of yield was 3.0 t ha–1; in SGM, it reached 4.2 t ha–1, and it was 54.6% more than the mean value of AI and SAL, while N0 was not different from MIN of AI and SAL. ORG yield was lower and not different from NO in AI, where the lowest values of 1000 kernels weight, and hectolitre weight were also recorded. MIN and ORG increased the number of spikes per square meter: 27.0%, and 12.8% over N0, respectively, but ORG showed an 11.2% decrease compared to MIN. The 1000 kernels weight reached the highest values in SAL, without differences between N0, MIN, and ORG. The values of protein and gluten percentage were highest in AI and SGM (about 13.5%, and 11.7%, respectively), but without differences between ORG and MIN in the 3 sites for protein percentage. The worst value of the vitreousness was recorded in SAL (52.3%), six-fold more than that of AI (8.2%), probably due to the high rainfall. NUE reached the highest value in SGM in the first year, when it was significantly different from AI and SAL (0.036 vs 0.030 t kg–1). Overall, the effect of nitrogen fertilization type results sitespecific; indeed, organic fertilization had the same performance of mineral in the site with better soil (low clay content, high nitrogen, and organic matter content) and climate conditions. Highlights - Organic fertilization based on roasted leather was compared to mineral fertilization in three marginal environments for two years. - Effect of organic fertilization on wheat yield, grain quality and nitrogen use efficiency was site-specific. - Yield of plants organically fertilized was lower than mineral fertilization in the two environments less fertile and with a high clay content. - Nitrogen use efficiency of organic fertilization was lower than mineral in the two environments less fertile and with high content of clay.- Grain protein and gluten percentage were lower in the site with higher rainfall.
